Phone Camera Test – Check Focus, Lenses & Quality

What this test checks

  • Front and rear camera access
  • Autofocus speed and image sharpness

How to use it

  1. Start the camera and inspect the live preview.
  2. Switch between front and rear cameras when available.
  3. Move the phone through bright and dim areas while checking focus.

Understand your results

Compare near and distant detail

Clean the lens exterior gently and hold the phone steady. Move between nearby text and a distant object, allowing focus to settle. Repeat in good light before treating blur or noise as a defect; a browser preview is not a full-resolution photo-quality measurement.

Check lenses the browser cannot select

The camera permission prompt or device list may not expose every physical lens. Use the native camera app to inspect its available zoom modes, flash and saved photos. A successful browser preview does not certify all lenses or confirm original parts.
